I am 70 years old and my house caught on fire Christmas and now I have several people that have access to the key to my house. I live in a remote area and would like to monitor the area when I go to see my Grandkids.

I purchased two Pelco DX816-500, (16 ports and alarm ports), units from the University. They did not have the harddrive or software. I purchased the harddrives and softweare V2.0 and they should be here this week.

Can someone recommend what I will need to install 3 cameras outside and inside?
